Just thought I'd comment on the Mario Power Tennis charging aspect.
Listening to you guys made me realize I should have talked about this more in my review.
Greg is partially correct. It auto charges if you stop moving. It doesn't do it whenever yous top moving though. It only does it if you are in the path of an oncoming ball.
This was a little weird at first, but I think the reason why it didn't make it into the review is because I got used to it. Personally, i think the auto charging is a good way to give the player feedback for if they are in the path of the ball.
There's one interesting part regarding forehands and backhands and this too. Your player will start auto charging whatever shot it thinks make sense. Obviously if its charging a back hand and you perform a back hand it will hit a nice hard shot...
However, if it is charging a backhand and you swing a forehand, your character will immediately jump to the other side and do a forehand... the result is still a return, but instead of a nice charged one, it's usually some sore of loop shot that will get spiked back in your face.
So yeah, forehand backhand selection is a level of depth that wasn't in the Cube game.
